The purpose of this study was to develop an interview instrument for school systems to use in the hiring process for school psychologists. The current professional standards, guidelines for practice, and existing literature were reviewed, which yielded consistent agreement of 10 interrelated domains that address essential skills and knowledge necessary to be a school psychologist practitioner. Interview items were constructed to assess proficiency across these 10 domains. A sample of 41 school psychologists volunteered to pilot the interview instrument. Interviews were conducted using interview questions, and responses were scored for each question using a 3-point rubric. To provide a measure of concurrent validity, an independent rating of the psychologist's skills was obtained from each psychologist's current supervisor. It was found that practitioners who obtained higher average scores on the interview were rated significantly higher by their supervisors (r = 0.51). It is suggested that this type of structured interview instrument, with items based on essential skills and knowledge to be a school psychologist, holds promise in assisting those conducting interviews to reliably gather useful information about a candidate's skill and knowledge set when making hiring decisions.
